The components of the system include the conduit anchor that secures to the instrumentation or spine; conduit housing through which leads enter and channels are isolated; the conduit cap to protect the implant; the lead adaptor entry port, wherein leads enter and channels are isolated; the lead adaptor pin housing, which contains contact pins; the keyed MIS tube, through which the lead adaptor is implanted in a second surgery; a grooved applicator to assist with lead placement; and an encircling clip to assist in securing a lead. The method of generating a signal in the frequency domain is described. The method of minimally invasive stimulation trial placement is described.

A stabilizer sleeve is disclosed for use with cardiac implantable electronic device leads. The sleeve comprises a tubular body sized to receive the lead and shaped to bias the lead toward a desired anatomical location, thereby reducing migration, dislodgement, and interference with cardiac structures. The sleeve may be introduced with the lead as a unitary assembly or added after lead placement. Various embodiments include a slitted body for expansion, radiopaque markers for visualization, detachable nose-cone tips for guidewire tracking, and antimicrobial coatings. The sleeve may be formed of polymers, alloys, or composite materials, and may include features such as texturing or anchoring projections for tissue engagement. Applications include positioning within a tricuspid valve commissure to minimize regurgitation and stabilizing left ventricular leads within branches of the coronary sinus. The device and methods described provide improved long-term stability and performance of implanted cardiac leads.

Apparatus, systems, and methods are provided for placing pacing leads or other devices within a patient's heart. In an exemplary embodiment, the apparatus includes a tubular member comprising a flexible distal portion defining a curvilinear shape in a relaxed state including a curved first region defining a first radius lying within a first plane, a substantially straight second region extending from the first curved region defining a first length, and a curved third region extending from the second region defining a second radius smaller than the first radius.

A method may include identifying a simulated three-dimensional representation corresponding to an internal anatomy of a subject based on a match between a computed two-dimensional image corresponding to the simulated three-dimensional representation and a two-dimensional image depicting the internal anatomy of the subject. Simulations of the electrical activities measured by a recording device with standard lead placement and nonstandard lead placement may be computed based on the simulated three-dimensional representation. A clinical electrogram and / or a clinical vectorgram for the subject may be corrected based on a difference between the simulations of electrical activities to account for deviations arising from patient-specific lead placement as well as variations in subject anatomy and pathophysiology.

A system and method for locating and guiding a peripheral nerve assessment (PNE) lead. The system includes an X-ray system for capturing an image of a patient. The image is processed by the system and provided to the user to use a measurement device to insert a needle for placement of a lead to perform the PNE process.

A system may include an electrode arrangement and a neurostimulator. The electrode arrangement may have a length typically in a head-tail direction and a width typically in an inboard and outboard direction. The electrode arrangement may include a first set of electrodes and a second set of electrodes spaced apart over a width. The neural stimulator may be configured to stimulate a series of locations of the patient using a subset of the first set of electrodes and, for each stimulated location in the series of stimulated locations, identify a respective response measure for each of the second set of electrodes. Physiological midlines may be inferred or identified from these measurements, which may be used to guide lead placement and / or programming.
